I would recommend getting a Japanese import pressing of the original album. I have done extended listening tests to various types of "audiophile" pressings, and in all cases, I preferred the "regular speed" over the "half speed". The only "audiophile" records I like better than the standard issue on virgin vinyl, are the "direct disc" recordings And some of them are not even that good. With the Japanese imports, you get the original mastering, combined with virgin vinyl, which IMO, gives the best sound with the least record noise.
